BLSPR Limit Switch is a type of limit switch used in industrial machinery and manufacturing. It is designed to detect the position of an object and to initiate an action when the object passes a certain point. The BLSPR Limit Switch is a non-contact switch that uses a magnetic field to detect the presence of a metal target. It has two parts, the actuator and the target. The actuator consists of a permanent magnet, a sensing coil, and a switch. The target consists of a metal target and a ferromagnetic material. When the target is in the presence of the permanent magnet, the sensing coil detects the change in the magnetic field and triggers the switch. The BLSPR Limit Switch is used in a variety of applications such as in safety systems, machine guarding, and process control.
